Abstract

PURPOSE:To collect mud in a pipe without stirring it by closing the tip of the pipe by using a wire in a state that a mud collecting pipe is forced into the bottom of water. CONSTITUTION:A mud collecting machine is supended by a wire 1 from a ship. The wire 1, a hook ring 3 and a mud collecting machine suspending lot 2 are connected. The lot 2 is inserted into mud collecting machine holding cylindrical metallic fitting 4. A check pin 7 is hooked to a cylindrical groove 2a of the lot 2. Tip metallic fittings 16 and a weight 21 are provided on a mud collecting pipe 18, and the pipe 18 is attached to the lot 2 by the metallic fittings 4. The tip metallic fittings 16 are connected to the ring 3 by a wire 11, and when the mud collecting machine reaches the bottom of water, the pipe 18 is forced in by its empty weight. Subsequently, the pin 7 is detached by a spring 6. On the other hand, when the wire 1 is lifted, the wire 11 is drawn, and the tip of the pipe is closed by the metallic fittings 16.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a hanging device for a mud collecting machine that collects mud from the bottom of the water.

It is required to collect mud deposited on the water bottom without disturbance and to investigate its condition. Conventionally, when inserting a collection pipe almost perpendicularly into the water bottom, mud was collected by rotation while inserting it. However, this disturbs the mud that is being collected, and even if a weight is placed in the case attached to the top of the sampling pipe and the pipe is forced into the bottom of the water by the weight of the collecting machine, the mud from the bottom of the water will be disturb. When pulling out a pipe, even if a check device is used at the tip of the pipe, it is inevitable that the collection core will be disturbed or fall off.

To prevent these disturbances and falling off, it is possible to completely prevent disturbance of the collected cores by closing the top and bottom of the pipe that has been press-fitted to the bottom of the water while it remains stationary before the pipe is pulled up, and then pulling it up.

The present invention has been developed in view of this situation, and when suspended by the retaining pin inserted into the circumferential groove of the hanging rod, the weight of the mud collecting machine will cause the machine to be suspended from the cylindrical metal fitting. The rods are connected, but as soon as the sludge sampling machine reaches the bottom of the water, the weight of the sludge sampling machine disappears, and the load on the stop pin that connects the cylindrical metal fitting for holding the sludge sampling machine and the hanging metal fitting disappears, and the stop pin is suspended by the spring. It fell out of the circumferential groove of the hanging rod, and the connection between the cylindrical metal fitting for holding the slurry sampler and the hanging rod came off.It was passed vertically through the center of the hanging rod, and the upper and lower ends were tightened and fixed with metal fittings, and the lower end was attached to the top of the tightening metal fitting. The hanging rod and the slurry extractor are connected only by a wire with a stopper. When pulling up a pipe that has been press-fitted to the bottom of the water by the weight of the sludge extractor, first, while the pipe is stationary, only the hanging rod rises until the wire stopper applies weight to the lower part of the cylindrical metal fitting that holds the sludge extractor, and during that time, the pipe is suspended. The wire connecting the locking ring on the rod and the closing device at the tip of the pipe is pulled, and the tip of the sampling pipe is closed while the sampling pipe remains stationary, inserted into the bottom of the water. After the closure is completed, the main body of the sampling machine is closed. It can be lifted by a wire passed through a hanging rod. The present invention provides a device for suspending a mud sampling machine.

An embodiment of the present invention will be described below with reference to the drawings.

In the figure, the hanging device is connected to a hanging ring 3 by a hanging wire 1 lowered from the ship, and the hanging ring 3 and the hanging rod 2 are connected, and the hanging rod holds the slideable body of the sludge collecting machine. A cylindrical metal fitting 4, a stop pin 7 that is perpendicular to the side surface of the cylindrical metal fitting 4 and moves back and forth toward the center, a metal 5 that holds it in the center direction, and a spring 6 that removes the stop pin 7 from the circumferential groove 2a of the hanging rod. The presser washer 8, the presser metal fitting 9 that keeps the stop pin 7 inserted into the circumferential groove 2a, and the lifting wire 10 passed through the center of the hanging rod.
The body of the mud sampling machine, which has a weight 21 consisting of fixed cylindrical fittings 10a, 10b and stoppers 10c at its upper and lower ends, is fixed to the cylindrical metal fitting 4 for holding the body of the mud sampling machine with three equally spaced rods 20. In addition, the pipe tip mud closure device is linked to the upper hanging device by a wire 11, and consists of a tip metal fitting 16, a rotating ring 12, and a cylindrical cloth 13 that connects them. A pipe 18 and a connecting bar 19 are arranged.

Next, this effect will be explained.

The mud collecting machine suspended from a hanging wire 1 from the ship is connected by a stop pin 7 inserted into a cylindrical groove of a hanging rod 2.
It is fixed by the bottom groove of the cylindrical groove 2a and the tip of the stop pin 7. After that, return the screw of the presser metal fitting 9 to a place where the rear end of the stop pin 7 does not come into contact with the stop pin 7 if it comes out of the circumferential groove of the hanging rod 2. When the tip of the slurry machine is press-fitted into the water bottom and the load on the stop pin 7 of the hanging device is removed, the stop pin is removed from the circumferential groove 2a of the hanging rod 2 by the force of the spring 6, and after the pipe is press-fitted, the stop pin 7 is removed from the circumferential groove 2a of the hanging rod 2. When the wire 1 is lifted, the lower rotating ring is rotated by the connecting wire 11 until the stopper of the wire passed through the center of the hanging rod 2 touches the lower end of the cylindrical metal fitting holding the mud collecting machine body, and the cylindrical cloth 13 is rotated, and the tip is closed. The mud collected by the pipe is lifted onto the ship via wire 10 and wire 1 in an undisturbed state.

As a result of the above, this suspension device can maintain the height of the sludge collecting machine to a minimum, prevent the lifting wire from getting tangled, and provide a suspension device that can be easily hung on board a ship. .
